Tears from severe coma with brain hemorrhage are not because the patient is sad. Patients in severe coma with brain hemorrhage have no autonomic consciousness and no perception of changes in the internal and external environment, so not only there is no joy or sadness, including any painful stimuli, so tears cannot mean that the patient is sad, sad or has other emotions. The main causes of tears in patients with severe coma from cerebral hemorrhage are the following: 1. Bulbar conjunctival edema: cerebral hemorrhage may be followed by cerebral edema and increased intracranial pressure, causing bulbar conjunctival edema, which manifests as involuntary tearing of the eyes; 2. Eyelid not closed: in patients with severe coma from cerebral hemorrhage, loss of consciousness leads to lack of muscle tone of the orbicularis oculi muscle and loss of generalized muscle tone, which leads to inability to close the eyelid, which in turn makes the cornea long-term Exposure to air can easily cause tearing; 3. Parasympathetic excitation: Patients with cerebral hemorrhage in severe coma may experience parasympathetic excitation, causing increased secretion of the lacrimal gland, which can lead to tearing. For patients with severe coma with cerebral hemorrhage who have tears, eye care should be strengthened. For those whose eyelids cannot be closed, saline gauze can be used to cover the eyes to prevent dryness or infection. Avoid contact with the eyelids when wiping the patient’s tears to avoid irritation or infection. In addition, for patients in severe coma, family members should provide basic care, such as regular turning and scrubbing, to prevent complications such as decubitus ulcers, pneumonia, urinary tract infections, and venous thrombosis of the lower extremities. At the same time, nutrition can be enhanced, and nasal feeding can be given according to medical advice.
